The volcano's lava dome has filled the inner crater, CENAPRED observed during an overflight on 27 January. The high level of the dome explains the relatively strong glow visible at night. ...plus

According to CENAPRED, it is likely that small to moderate explosions in the coming days will destroy the dome again (as happened numerous times in the past during the current eruptive cycle of Popo).During the past few days, activity has been at average to low levels with 2-5 small explosions that generated ash plumes dispersing into easterly directions.

Karymsky (Kamchatka): The typically intermittent explosive activity at the volcano has been elevated during the past days. Several ash plumes up to altitudes of up to 22,000 ft (7 km) have been reported by Tokyo VAAC during the past days. ...plus

Dukono (Halmahera): The volcano continues to produce near-continuous ash emissions from its crater, that generate plumes drifting up to 100-150 km in various directions. [moins]

Our local expedition leader informed us about increased volcano-tectonic activity along the Ethiopian part of the East African rift: a new lava overflow at Erta Ale and a 4.2M earthquake near Corbetti caldera. ...plus

In the Danakil depression, northern Ethiopia, the continuously active lava lake at Erta Ale started to overflow on the 27th of January. This latest overflow created new pahoehoe lava flows that cover Erta Ale´s caldera floor both to the north and south of the lava lake´s eruptive vent. At the moment of writing this news item, the lava lake is thought to be still overflowing. It is however unclear for how long this phase of lava overflow will continue.

Bromo (East Java, Indonesia): According to a local news article referring to information from the volcano observatory, the volcano's eruption started to eject visibly incandescent lava bombs this morning.

No significant changes have occurred during the past weeks at the volcano. Magma is slowly rising and growing a flat dome in the inner summit crater. Trapped, pressurized gasses cause small to moderate explosions with more or less intense ash emissions from time to time, typically a few per day: ...plus

According to a local news article referring to information from the volcano observatory, the volcano's eruption started to eject visibly incandescent lava bombs this morning. ...plus

In more technical words, this suggests that by now the eruption entered a so-called magmatic phase where fresh lava arrives at the surface (as opposed to ash emissions from mostly pulverized older rocks, which might have been the activity so far). The head of the Center for Volcanology and Geological Disaster Mitigation, Edi Prasojo, said that" Bromo has entered an eruption phase", the article mentions.On a side note, incandescent ejected rocks alone, however, do not necessarily (although often) mean that they are from fresh magma. In some cases, they can also be older, very hot rocks from the conduit ejected by phreatic activity). An analysis of a sample or the ash would tell the difference. [moins]

No significant changes have occurred in the ongoing eruption both at the volcano's summit and on its eastern rift zone. Degassing, seismicity and deformation are at normal levels. ...plus

Summit lava lake: The lava lake in Halema'uma'u continues to be active, fluctuating in level around 35 m below the crater rim.Puʻu ʻŌʻō (East Rift zone): A small new circular lava pond, approx. 20 m in diameter, has formed in mid January in the western end of the crater.

Fuego (Guatemala): Another phase of increased explosive activity and lava effusion is taking place at the volcano. Small pyroclastic flows were observed this morning. ...plus

After the violent phase during the first days of 2016, this is the second paroxysm of the volcano this year already. Over the past months, such phases have occurred at astonishing rhythmic intervals of 3-4 weeks (see the peaks on the thermal signal graphic).

Egon (Flores): An eruption warning remains in place. Increased sulfur smells have been noted from the volcano which had been raised to second highest alert on 13 Jan. ...plus

According to local news, evacuation of 3 villages at the feet of the volcano are taking place and so far, 1200 people have been relocated and 2000 dust masks have been distributed (in case of ash emissions). The exclusion zone around Mt Egon volcano is 3 km radius from its summit only (but in case of a larger eruption, this should be drastically increased, especially around rivers draining from the mountain.)

The lava lake of Erta Ale has overflown, our correspondents from Ethiopia reported. The first lava over-spilled the rim of the containing crater at midnight of 15-16 Jan 2016. It seems that the situation is similar to the spectacular events in November/December 2010 when the lava lake last overflowed. ...plus

More details and images will be posted as soon as possible. During our expeditions in Nov and Dec, the level of the lake had already been occasionally as close as only 1 meter beneath the rim.If you like to join with short notice on this exciting trip, we still have some spaces left on the 7-20 February expedition.

Karymsky (Kamchatka): Activity at the volcano, in continuous intermittent explosive activity for many years, seems to be elevated at the moment. Several explosions have been reported during the past days through observations of ash plumes reported reaching up to 18,000 ft (5.5 km) altitude (Tokyo VAAC). ...plus

Nishino-shima (Volcano Islands, Japan): The eruption seems to have ended in mid December. During the past two visits of the Japanese Coast Guard on 27 Dec and 3 Jan 2016, no more eruptive activity has been noted.

A new phase of eruptive activity began at the volcano on Monday. Accompanied by a spike in volcanic tremor, weak to moderate ash emissions have been occurring from the main crater. This activity, the 22nd eruptive phase since Dec 2013 according to MARN, has been decreasing since yesterday.

Since its last (relatively weak) paroxysm during the first days of 2016, the volcano has now been unusually calm. According to this morning's status report of the observatory, no explosions have been seen (or heard) since 5 days... ...plus

The two years of eruption since late November 2013 increased the size of the island from its tiny 0.26 to approx. to 2.63 square km. Now, it is up to the waves to slowly eat away at the young shores and gradually decrease it again, until a next eruption occurs...

A short pulse of ash emissions occurred in the evening of 8 Jan 2016 around 18:49 local time. ...plus

No further emissions have occurred since and it is believed that the event was caused by phreatic activity of the shallow hydrothermal system of the volcano (not by fresh magma).Sernageomin raised the alert status of the volcano to yellow. [moins]

The volcano's eruption continues with little changes into its third year. Slow lava extrusion at the summit results in occasional small to moderate pyroclastic flows as well as sporadic explosions. ...plus

This activity occurs in weeks-to-month long alternating phases of more and less intense frequency, as lobes of the overspilling dome grow too large and then break off to generate a series of collapses within a shorter time.Both the pyroclastic flows and explosions produce ash plumes that regularly rise a few km above the volcano and are often reported by Darwin VAAC.

Ash from the volcano has been observed on satellite imagery during 11-12 Jan, Darwin VAAC reported. Likely, this came from a larger rockfall triggering a small pyroclastic flow, but this needs to be confirmed. The latest VSI report from this morning only mentions continuing glow from the active summit lava dome and small to moderate rockfalls. ...plus

In case of heavy rains, larger rockfalls and lahars could occur, in particular towards the valleys radiating to the SE from the volcano. Seismic activity remains elevated with an increase in shallow volcanic quakes. [moins]

The volcano remains at significant unrest and moderate to large explosions could occur any time, the latest evaluation report of the volcano observatory states and alert level is being maintained at 3 ("siaga") on a scale of 1-4. ...plus

During the past weeks, visual activity consisted in degassing creating a plume of 25-150 m above the Tumpalun crater. Seismic activity has been dominated by frequent shallow volcanic earthquakes (up to 21 per day), sometimes felt nearby.No clear trend has been visible over the past two weeks. [moins]

Soputan (North Sulawesi, Indonesia): A powerful explosive eruption occurred at the volcano during 4-6 January. It began with a series of at least 4 powerful explosions between 20:50 on 4 Jan and up to the next morning, producing tall ash plumes that rose 4-6 km above the volcano and drifted north. ...plus

... [read more] ... [show less]At least some of the explosions also triggered pyroclastic flows reaching the southern base of the summit cone. Moderately strong ash fall of 1-2 cm occurred in villages about 10 km to the NE of the volcano.

The lava flow effusion and continuous strombolian activity had stopped in early December, followed by only high-temperature degassing, sporadic minor explosions and the growth of what might have been a small lava dome. A more intense phase of activity seems to have started yesterday. Early on 2 January, small ash emissions occurred, followed by more, still weak explosions in the early afternoon of yesterday.The strong explosion this morning might have involved a small pyroclastic flow on the NE side of the volcano, reaching about 1.5-2 km length. [moins]

Fuego (Guatemala): (1 Jan) Activity at the volcano has remained at similar levels (if not decreased a bit) as during the past days. ...plus

When observed during the past night and this morning, strombolian-type explosions of small to sometimes strong intensity ejected abundant incandescent bombs in all directions from the summit vents. A small lava flow is active on the upper SE flank, producing often continuous glowing rockfalls that travel up to approx. 1 km towards the Las Lajas ravine.No new pyroclastic flows were observed. Overall, activity seemed to be on a slowly decreasing trend. [moins]
